Document Type and Number:
WIPO Patent Application WO/1999/011846
Kind Code:
A1
Abstract:
A coiled carbon fiber of 0.01-5 $g(m)m in fiber diameter, 0.1-2000 $g(m)m in coil diameter, 0-50 $g(m)m in coil pitch and 100 $g(m)m-5 m in coil length, including a coiled carbon fiber having a clockwise-twined double spiral structure and a coiled carbon fiber having a counterclockwise-twined double spiral structure; and a method of manufacturing the same, comprising placing a metal catalyst, a gas of a compound of an element of the group 15 or 16 in the periodic table and a sealing gas in a reaction tank, and heating hydrocarbon or carbon monoxide to a temperature of 600-950 °C while applying an electrostatic field thereto to decompose the hydrocarbon or carbon monoxide and obtain a carbon fiber grown to the mentioned shape.
